Reverts rubocop/rubocop-ast#198

Re-enables running rubocop 0.92's tests in CI.

@marcandre I guess we need a backport for v0.92 (or v0.93?) in order to make the tests there pass?

You'll have to bump 0.92 => next RuboCop version (and we'll merge when it is released)

I don't think we can do much tbh. It's ok, it is unlikely we'll break compatibility in a real fashion anyways.

Is this still needed?

[marcandre]

Ideally yes. I'll try tweaking things in #264
